Szczegółowy opis
Executive functions, including inhibitory control, working memory, cognitive flexibility, and attentional control, play an important role in sports requiring rapid perception and decision-making, such as volleyball. Although previous studies have shown that cognitive training can improve executive functions, evidence regarding the transfer of these improvements to sport-specific performance remains inconsistent.
The purpose of this randomized controlled study is to investigate the effects of a short-term tablet-based cognitive training program on executive functions and volleyball-specific on-court decision-making performance in adolescent female volleyball players.
Fifty licensed female volleyball players aged 12 to 14 years participated in the study. Participants were randomly allocated to an intervention group or a control group. The intervention group completed a four-week cognitive training program consisting of three supervised sessions per week (20-30 minutes per session) in addition to routine volleyball training. The control group continued routine volleyball training without additional cognitive training.
Primary assessments included executive function measures obtained using the Stroop Test, Trail Making Test-A (TMT-A), Go/No-Go Test, and 2-Back Test. Volleyball-specific decision-making performance was evaluated using a video-based temporal occlusion paradigm, with decision-making accuracy and response time recorded before and after the intervention.
The study aims to determine whether short-term cognitive training improves executive function performance (near transfer) and whether these cognitive improvements translate into enhanced sport-specific decision-making performance (far transfer) in adolescent female volleyball players.

Eksperymentalny: Cognitive Training Group
Participants received a four-week tablet-based cognitive training program (20-30 minutes/session, three sessions/week) in addition to their routine volleyball training.
|
A structured four-week tablet-based cognitive training program was administered three times per week for approximately 20-30 minutes per session.
The program included computerized exercises targeting inhibitory control, working memory, cognitive flexibility, attention, and processing speed using validated cognitive training applications.
Participants continued their routine volleyball training according to their regular training schedule.
